Cross‐Phase Modulation via Time‐Varying Epsilon‐Near‐Zero Metasurfaces
Advanced Optical Materials, EarlyView.Time‐varying epsilon‐near‐zero metasurfaces are shown to enable cross‐phase modulation beyond conventional ENZ excitation. By engineering dual absorption bands and exploiting oblique ultrafast pumping, large and broadband frequency translations are achieved at low pump energies.

Advanced Optical Materials, EarlyView.Possibilities for ablation‐free microforming of borosilicate glass using ultrashort laser pulses are presented. Depending on the laser parameters and scanning strategy, surface structures with profile heights of up to 20 µm could be produced. The work provides a comprehensive experimental and analytical characterization of the microforming process ...

Controlling Ultrafast Photonic‐Plasmonic Coupling in a Hybrid Platform for Biosensing Applications
Advanced Optical Materials, EarlyView.A metal–dielectric hybrid composed of gold nanocaps on opal exhibits a broad near‐infrared plasmonic resonance interacting with the photonic bandgap under ultrafast transient conditions. This coupling can be controlled by varying the excitation wavelength and is responsive to bacterial deposition, opening new opportunities for ultrafast biosensing ...

Strong Plasmon–Exciton Coupling Tuned by Corner Etching of Gold Nanocubes and Nanotriangles
Advanced Optical Materials, EarlyView.Systematic etching of gold nanocubes (AuNCs) and nanotriangles (AuNTs) reveals how nanoparticle morphology governs plasmon–exciton strong coupling. While rounding the corners of AuNCs weakens their coupling, triangular geometries robustly preserve deep strong coupling.
